BOTTLE-CLOSURE.

Specification of Letters Patent.

Patented Aug. 6, 1.907.

Application filed January 11,1907. Serial No. 361,864.

To all 'whom it may concern:

Be it known that I, FRANCIS W. H. CLAY, a citizen of the United States,residing at Pittsburg, county of Allegheny. in the State ofPennsylvania, have invented certain new and useful Improvements inBottle-Cloessary to effect the seal, and in which also the securingmeans for holding on the stopper is devised to induce this pressure ofits own accord, in the process of placing the stopper on the bottle.

The objects of the present invention are to provide a more securelocking device for the holding members of the stopper, to provide formore efiicient action in applying the pressure, and to provide for easyremoval of the stopper. These objects and other advantagesare gained" bythe structure illustrated on the accompanying drawing. I

Figures 1 and 2 are respectively a side elevation and a top plan of thestopper before placing on the bottle. Fig. 3 is a side elevation of thestopper wired in place. Figs. 4 and 5 are vertical central sections online (4) in Fig. 2, showing the stopper before it is fastened andafterward respectively. Figs. 6 and 7 are respectively a side elevationand a top plan of a modified form of a stopper designed for easy openingby the fingers. Fig. 8 is a view of the same stopper in place on thebottle. Fig. 9 is a side elevation of a modified form of constructionand Fig. 10 shows a section of the packing disk-I prefer to use'.

In Figs. 1 to 5 the covering-disk 11 is provided with a down-turnedflange which has portions at intervals separated from the body anddepressed to make gripping arches 12. These arches have extending arms13 which form levers for pushing and holding down the arches 12. Themetal of the flange betweenthe downward arches 12 is arched upward andpreferably also slightly indented as at 14, so that when the arms 13 arepushed downward the lever action forces the arches l2 inward to gripupon the bottle head and induce avertical pressure on the packing disk16, while the metal of the upper arches may fold inward, at 14, as shownin Fig. 3. It will be evident from Figs. 4 and 5 that when the arms 13are pushed downward and inward the edge of the arch of metal 12 will beforced under the lip of the bottle head and result in a drawing downwith great power, of the top covering disk 11 of the stopper. It is alsoevident that the engagement with the bottle will be resilient and thatthe edge of the metal 12 will automatically find its own seat and by itstendency to spring back to normal position will maintain a constantlyexerted resilient pressure. The arms 13 may be held down for additionalsecurity by means of. a wire orband 15. When desired the band may beused to push down the arms 13. This form of stopper is more especiallydesigned for bottles containing liquid under very heavy pressure of gas.7 v

In Figs. 6, 7 and 8 is shown a form of stopper in which the grippingarches 12 are held downward by means of the folding in of the metal at14 and 14a, at the apex 1 of the upward bent arches. It is thusself-retaining, after being put 011 with a. tool which affects thischange of form. This feature has been covered in my prior patents, but Ihave now added to it the feature of the extended lever arms 17 each ofwhich forms a continuation of two of the gripping arches 12 so that thestopbent downward when the three gripping arches to which the extension18 is attached, are bent down. In the use of these stoppers on beerbottles and in other places where an impervious stopper disk isnecessary and where the packing disk must be subjected to heat, I findthat a very excellent packing disk is made as illustrated in Fig. 10,inwhich the part 16 is some fibrous material such as paper pulp and on itis placed a facing 16a of such material as pyroxylin. The soft pyroxylinmay readily conform to the surface of the glass, while the paper partmay be harder and of sufficient thickness to take up any unevenness inthe surface of the glass.

In these forms of the stopper it is to be noted that the placing toolfor applying them may engage only the upward bent arches of the cap andby pushing them downward and inward the gripping arches 12 are swunginward and upward and meanwhile the folds of metal at 14, and 14a maytake up the extra metal and are free to fold as much as necessary underthe pressure. When the operation is completed, the folds 14 form veryshort, sharp bends and when the tool is removed the spring back of themetal which always takes place when any bend of metal is changed inform, will be more than compensated for by the relativelylarge arch 12whose tendency to open is counteracted by the open- Having thusdescribed my invention, and illustrated its use, what I claim as new anddesire to secure by Letters Patent is the following.

1. A metallic bottle closure comprising a covering disk having adownwardly bent flange separated at intervals from the disk, theseparated portions thereof being depressed to form gripping arches, andextended arms upon 4. A metallic bottle cap having a flange with severeddownwardly bent arches adapted to engage a bottle head, said archesbeing connected by upward bends integral with the cap and indented tofold inwardly at their apexes when all the arches are pushed downward,some of said gripping arches being provided with lever handles, subthearches for moving them to apply or release the stopper.

2. A bottle closure comprising a covering disk having a depressedradially fluted flange with the downward bends thereof severed from thecover, and extended rigid arms on said downward bends forming levers.stantially as described. 6

3. A bottle closure comprising a covering disk having a In witnesswhereof I have hereunto signed my name in radially fluted flange withthe downward bends thereof the presence of the two subscribed witnesses.severed and depressed to engage the bottle head by the FRANCIS W. H.CLAY. edge of the metal, said downward bends having outward leverextensions, and a band 15 to hold said extensions down, substantially asdescribed.
